Lost count but thousands - at one point there were around 3,500 quakes on the Cali/Baja map for the week. That was a week or so ago and, as you say, they're still going...



Ok, so 3500 was for 1 week? A week or so ago? Incredible. I had the mis-understanding that the count that was going on in this thread was the *total* (for some reason) from the time of the quake.. So we're talking tens of thousands. Ridiculous!

Yeah, that article I was talking about was from over a week ago..

Not a lot of detail, and not very recent either.

Ok, So I guess I'm slightly confused. So the official count a week or so ago *from* the time of the intial quake was around 3k?

I'm confused because I'm wondering if the counts on here were for the *week* ( quakes generated in that one week) or the count of ALL aftershocks from the time of the 7.2


Edit for further clarity:




at one point there were around 3,500 quakes on the Cali/Baja map for the week

I'm a little confused too. I admit that I'm very new to this, and at this point addicted to say the least..

No worries, I'm equally confused. That's why I love ATS because we have some serious experts out there to halt that confusion.

Go back one page and look at my post. The total - FROM the time of the 7.2 - is just under 5000.

Thank you!
(it was me who asked. :p ) Not as insane as I was seriously about think...but still pretty crazy IMO! Then again what the hell do I know.


AND I have a seriously BAD habit of overlooking your posts/replies for some reason.. They seem to show up WAY later for me. That, or I'm just going blind!

Last question for you Puterman! Are 5k aftershocks normal within (less than) a month of a 7.2? Sorry, I'm still learning this EQ lingo.

Wow, that is amazing. Sounds like a pretty high number to be normal. Thanks for pointing out what you already pointed out.


Ok, I'll stop with the side chatter.. I don't want to get anyone pissed at me for derailing the purpose of the thread. Thanks again for your contributions all the same.

He's gone to bed, so I'll try this one


Because the quake was situated pretty much in the US, or in a region USGS report quakes 2.5 and over (instead of the rest of the world where they usually limit to reporting quakes over 4.5), there were far more quakes reported than, say, after the Chile or China quakes. Hence the large numbers being listed.

Big quakes do spark off lots of aftershocks - as to what is normal, I'm not sure there's an average no. used for comparison anywhere.

Having not watched a U.S. quake that big before on USGS I'm not sure whether 5,000+ being reported is excessive or not. I'm thinking not.

FYI - here's the USGS main aftershock map (covering 48 hrs from main 7.7) earthquake.usgs.gov...,%20Mexico

Just my 0.02cents

Magnitude 6.2 (Preliminary magnitude — update expected within 15 minutes)
Date-Time

* Wednesday, April 21, 2010 at 17:20:31 UTC
* Thursday, April 22, 2010 at 06:20:31 AM at epicenter

Location 15.239°S, 172.828°W
Depth 32 km (19.9 miles) set by location program
Region SAMOA ISLANDS REGION
Distances

* 198 km (123 miles) SW (216°) from APIA, Samoa
* 253 km (157 miles) WSW (244°) from PAGO PAGO, American Samoa
* 399 km (248 miles) NNE (18°) from Neiafu, Tonga
* 2493 km (1549 miles) W (272°) from PAPEETE, Tahiti, French Polynesia
Event ID at00187043


Downgraded to 5.9


Problem with that downgrade is the location.
Was originally stated in Samoa then when downgraded
the epicenter moved 557 miles to Tonga. How can
this be considered the same event???


I din't see the original event on USGS, I seen it first on GEOFON when I opened up, and it said Tonga there, so I can't comment.

My take would be that although the event was physically closer as the bird flies to Samoa than to the main islands of Tonga, the event was on the Tongan Plate rather than the Pacific Plate ( where Samoa is).
Or maybe they are measuring the distance to the most northern Tongan island of Tafahi which is only 109km away.
This is something I never noticed before, but it adds up when you look at the location of the September 29, 2009 Samoa 8.1 (the one with the Tsunami) It was closer to Tonga in distance, but because it was on the Pacific Plate ........ it got called the " Samoa Quake"

Helps if you have Google Earth and open the Earthquakes layer under Gallery, and also use the kml download from USGS for the last 7 days (here)
